Early season natural biological control of insect pests in rice by spiders-and some factors in the management of the cropping system that may affect this control

  title={Early season natural biological control of insect pests in rice by spiders-and some factors in the management of the cropping system that may affect this control},
  author={Lene Sigsgaard},
There are relatively few insect pest problems in unsprayed, irrigated rice. Spiders are numerous early season predators and are thought to play an important role in the suppression of insect pests such as plantand leafhoppers. Pest resurgence after insecticide spraying has been clearly linked to the negative impact of insecticides on spiders and other natural enemies. In particular, recent studies show that spiders depend on detritivores for food during fallow periods. The relatively low prey… 

A Brief Overview of the Rice Pests and Their Natural Enemies in Some Rice-Growing Asian Countries

The results showed that the majority of rice pest predators were from Hemiptera and Arachnidae and the main parasitoids were hymenopterans that attacked various life stages of their hosts.

Surrounding landscape influences the abundance of insect predators in rice field

It is suggested that predators of rice insect pests are landscape specific, and characterization of each local landscape in Bangladesh rice production landscapes are necessary before planning and implementation of integrated pest management.

Short-Term Effects of Conversion to Direct Seeding Mulch-Based Cropping Systems on Macro-Fauna and Weed Dynamics

The increase in biological control agents shortly after conversion to direct seeding mulch-based cropping systems suggested that cover crops should be considered as a pest management tool, even on a short-term scale.

Biodiversity and Dynamics of Planthoppers and Their Natural Enemies in Rice Fields with Different Nitrogen Regimes

The results indicated that the rapid growth in populations of planthopper due to excessive nitrogen might be attributed to the combination of reduction in control capacity of natural enemies and strong simulation of nitrogen to planthoppers.

Integrated Insect Pest Management Techniques for Rice

In modern agriculture, climate change, environmental degradation, and natural resource depletion constitute one of the major potential issues for sustainable crop production and environmental

Effect of the insecticide Lambda-cyhalothrin on rice spider populations in southern Brazil

The spider fauna in rice fields are adversely affected by the application of the insecticide Lambda-cyhalothrin, and Araneidae and Tetragnathidae dominated, and were both strongly affected by insecticide application.

Spider population and their predatory efficiency in different rice establishment techniques in Aduthurai, Tamil Nadu.

The role of spiders in regulation of insect pests has been studied in the rice ecosystem ADT 39 cultivated by different Rice Establishment Techniques and high population of spider in the different treatment plots limits the exponential growth of pest population.

Side Effects of Insecticides on Natural Enemies and Possibility of Their Integration in Plant Protection Strategies

Every crop is infested by various pests; some but not all of them may be controlled by biological means using pathogens, predators, parasitoids and spiders but to achieve a satisfactory control of complexes of pests, selective pesticides are also indispensable.

A Review on Brown Planthopper (Nilaparvata lugens Stål), a Major Pest of Rice in Asia and Pacific

Rice (Oryza sativa L.) is the most important staple food in the world including Asia and Pacific. Millions of people around the world depend on rice due to the high calories and economic returns it

The role of biodiversity in the dynamics and management of insect pests of tropical irrigated rice—a review

P pest management of much tropical irrigated rice must be based on natural controls rarely supplemented by insecticides, and there is no evidence that a natural control-based approach, as recommended in this review, is incompatible with farmer practicability or with future developments in rice production.

Interactions between Biological Control Efforts and Insecticide Applications in Tropical Rice Agroecosystems: The Potential Role of Intraguild Predation

Although adding either wolf spiders or insecticide to field plots significantly reduced abundance of pests, combining the two treatments together generated a significant, season-long interaction effect such that pest densities did not decrease, indicating that combining treatments of natural enemy addition and insecticide application may be quite counterproductive.

The Effects of Weed Residue Management on Pests, Pest Damage, Predators and Crop Yield in Upland Rice in Côte d'Ivoire

Spider density was greater when residue was piled or used as mulch rather than when scattered but the smallest populations occurred in the no-residue plots, and staphylinid beetle activity was significantly greater in plots with a supplementary weed mulch than in other treatments.

Managing Tropical Rice Pests Through Conservation of Generalist Natural Enemies and Alternative Prey

The results demonstrate the existence of a mechanism in tropical irrigated rice systems that supports high levels of natural biological control, which depends on season l ong successional processes and interactions among a wide array of species, many of which have hitherto been ignored as important elements in a rice ecosystem.

Insect pests of rice.

The rice water weevil is the most serious pest of rice in the US and is controlled by 3 seed treatments (Dermacor X100, NipSIt INSIDE and CruiserMaxx Rice) and various foliarapplied insecticides.

Impact of insecticides on herbivore-natural enemy communities in tropical rice ecosystems

Today, rice pest management in tropical Asia is strongly influenced by the agrochemical era of the 1960s and 1970s. Prophylactic insecticide campaigns were components of rice production

Extension challenges are a key topic for rice IPM research, and new pest management technology must promote, rather than endanger, ecological balance in rice paddies.

Crop Loss Assessment in Rice

Indirect damage from insect injury may slow or hasten the growth rate or allow pathogens to enter the plant.

Analysis of Invertebrate Biodiversity in a Philippine Farmer's Irrigated Rice Field

Rank-abundance curves, indices of community structure, and surrogate-based methods of biodiversity assessment were applied to invertebrate time-series data collected from a farmer's irrigated rice (
